1. The FDA Reality Check: Cleared vs. Approved

Before investing capital into a clinical device, you must understand your biological baseline. All top-tier devices on the market are FDA "Cleared" (Class II), which means they are proven safe and substantially equivalent to existing predicate devices. They are not FDA "Approved" (Class III), which is a classification reserved for high-risk surgical implants.

2. The Hardware: Lasers vs. LEDs

Not all light is created equal. The goal of Low-Level Laser Therapy (LLLT) is photobiomodulation—stimulating the cytochrome c oxidase in your follicle's mitochondria to produce ATP energy.

• ✅ Medical-Grade Lasers: Emit coherent, focused light that penetrates 3 to 5 mm deep into the scalp to reach the actual hair root.
• ❌ LEDs (Light Emitting Diodes): Emit non-coherent light that scatters superficially across the surface of the skin. While cheaper to manufacture, they fail to achieve deep follicular activation.
